JOHN A. FRENZEL, OF WAUSAU, WISCONSIN.

CUTTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,637, dated May 3,1904.

Application filed September 10, 1903. Serial No. 172,636. (No model.)

To all whom it may concern.-

Be it known that I, JOHN A. FRENZEL, a citizen of the United States, anda resident of VVausau, in the county of Marathon and State of Wisconsin,have invented certain new and useful Improvements in Cutting-Machines;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention has for its object to provide simple economical cuttingmachines, especially designed for the manufacture of smoking-tobaccofrom tobacco-stems. and cigar-clippings, but which may be utilized forcutting straw, the organization of each machine being such thatprovision is had for varying the length of cut. Hence said inventionconsists in certain peculiarities of construction and combination ofparts hereinafter particularly set forth with reference to theaccompanying drawings and subsequently claimed.

Figure 1 of the drawings represents a Vertical longitudinal section viewof a cutting-machine in accordance with my invention; Fig. 2, a sideelevation of the same having parts thereof broken away; Figs. 3 and 4,vertical transverse sectional views of the machine, re spectivelyindicated by lines 3 3 and 4 4 in Fig. 2; Fig. 5, a similar viewindicated by line 5 5 in Fig. 1; Fig. 6, a side elevation of a fragmentof the machine; Fig. 7 a plan view, partly in horizontal section, on theplane indicated byline 7 7 in Fig. 6; Fig. 8, a side elevation ofanother fragment of the machine, and Fig. 9 a sectional view indicatedby line 9 9 in Fig. 8.

Referring by letter to the drawings, Aindicates the feed-box of acutting-machine in accordance with my invention, the same being mountedon a suitable frame, that also supports parallel plates B B, set on edgeand arranged to constitute forward extensions of the sides of said box.A bracketC is mounted on the machine-frame parallel to each of theplates B, and rollers D E are journaled in the plates and brackets. Theshear-plate F of the machine is mounted on the aforesaid frame adjacentto the lower feed-roller D, and the brackets C are provided withbearings for the shaft G of a knife-cylinder H, that is run by hand orpower, as found most convenient in practice.

A fly-wheel I is made fast on one end of the shaft, and held indetachable connection with the other end of said shaft by a set-screw orotherwise is a spur-pinion J, it being intended that a set of suchpinions, variable in the matter of size, shall accompany each machine,to be interchangeable, for the purpose of varying the length of cut, ashereinafter further explained.

A housing K is provided for the knife-cylinder, and a chute L isprovided for the cut material.

Trained on the roller E and another roller M at the rear of the feed-boxis an endless apron N, thezstretches of which are above and below thebottom of said box. naled in bearings having screw-threaded shanks b,guided in brackets 0, fast on sides of the feed-box, and by means ofnuts d the stems are adjusted to regulate tension of the apron.

The journals of an upper feed-roller P have play in vertical slots withwhich the plates B are provided, and these journals have their bearingsin links 0, that are connected with arms of a rock-shaft q, suspended inbrackets f, depending from upper longitudinal members of themachine-frame. Suspended from a hook-arm g of the rocker is a hanger hfor a lever R, fulcrumed on a lower transverse timber of themachine-frame, and a weight S is adjustable on the lever to regulate thepressure of the aforesaid upper feed-roller.

Pivotally hung in vertical ears of a coverpiece T on the plates B is ahanger U for a pressure-roller V, that is held down over material on theapron N parallel to the roller E when the machine is in operation,manipulation of the roller V being facilitated by means of ahandle z',with which its hanger is provided.

Hung on a lateral stud j of the machineframe is a carrier W, providedwith a bolt 71:, engaging a segmental slot in a member on of themachine-frame, and a hand-nut n is run on the bolt to clamp the carrierin pivotally-adjusted position. A spur-wheel X is loose on the stud 1'outside of the pivotally-adjustable carrier, and the hub of thisspur-wheel is toothed forming a spur-pinion p, that meshes with aspur-wheel Y, fast on a journal of the The spur-wheel X meshes lowerfeed-roller.

The roller M is jourwith another spur-wheel X, loose on a lateral stud qof the carrier W, and loose on another lateral stud 0' of the carrier isa spur-wheel Z, that meshes with the pinion J when in working position.The hub of the spur-wheel Z is toothed to form a spur-pinion s, thatmeshes with the spur-wheelX aforesaid, and the spurwheelX is ofconsiderably less diameter than said spur wheel Z, both of which areadjustable with the carrier above specified.

At the power side of the machine spurwheels t t, fast on journals of therollers D E, are in mesh with an idler spur-wheel a, loose on a lateralstud o of one of the brackets C, the motion of roller D being thuscommunicated to the one, E, both rollers being run at the same speed inthe same direction. On the opposite side of the machine a spur-wheel wis fast on a journal of feed-roller D in mesh with an idler spur-wheelw, loose on a lateral stud of the adjacent bracket, this idler being ofsuflicient width of face to be also in mesh with another idler spur-wheel y, loose on another lateral stud of said bracket and in mesh witha spur-wheel 2, fast on a journal of the upper feed-roller, this gearingbeing such that said upper feed roller is driven at the proper speed inthe proper direction when the lower feed-roller has rotation.

The machine being assembled as shown in Fig. 1, the length of cut ofmaterial fed in the path of the knives will depend on the speed of thefeed apron and rollers, this speed being determined by the size of thepinion J, fast on the shaft of the knife-cylinder and in mesh with thespur-wheel Z when the latter is in working position as a result of aproper adjustment of the carrier W above specified.

By adjusting the pinion J of any size on the shaft Gof theknife-cylinder and putting the spur-wheel X in mesh therewith, as shownin Fig. 8, the length of cut will be greater than when said pinion ismeshed with the spurwheel Z aforesaid. Hence it will be understood thata pinion J of any suitable size may be used in connection with the shaftG of the knife-cylinder, and the length of cut of ma terial fed to saidknife-cylinder will be greater or less,according as said pinion ismeshed with one or the other of the spur-wheels X or Z above specified.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A cutting-machine comprising feed-rollers and a roller supported endlessfeed apron, gearing connecting one of the feed-rollers and one of theapron-rollers, a pressure-roller having a pivotal hanger and adjustabletherewith to be parailel to the geared apron-roller, spur-wheels ofdifferent diameters in connection with a pivotally-adjustable carrier,gearing connecting both spur-wheels with one of said feed-rollers, ashear-plate, a knife-cylinder, and a pinion adjustable on the shaft ofsaid cylinder to be meshed with one or the other of said spur-wheels.

In testimony that I claim the foregoing I have hereunto set my hand, atWausau, in the county of Marathon and State of \Visconsin, in thepresence of two witnesses.

JOHN A. FRENZEL.
